Choose C44300 when you need high heat transfer, low cost, and good biofouling resistance in clean seawater or fresh water at moderate velocities (1–3 m/s) and temperatures below 200°C. Nickel alloys are unnecessary overkill for these conditions – they cost 3–8× more, transfer heat poorly, and are difficult to fabricate into U‑bends.
